First record of Aedes albopictus (Skuse, 1894) (Diptera; Culicidae) from Minorca (Balearic Islands, Spain)

[eng] The Asian tiger mosquito is an invasive species showing a continuous expansion in the Mediterranean basin in general and in Spain in particular. The first detection of Aedes albopictus in mainland Spain was reported in 2004. Eight years later, in 2012, this mosquito species was detected in the Balearic archipelago, specifically on Majorca. In 2014 it was detected on Eivissa, another island from this archipelago. In this paper we report for the first time the presence of Ae. albopictus on the island of Minorca

The impact of indoor residual spraying of deltamethrin on dengue vector populations in the Peruvian Amazon

[eng] Dengue is an important public health problem in the Amazon area of Peru, resulting in significant morbidity each year. As in other areas of the world, ultra-low volume (ULV) application of insecticides is the main strategy to reduce adult populations of the dengue vector Aedes aegypti, despite growing evidence of its limitations as a single control method. This study investigated the efficacy of deltamethrin S.C. applied through indoor residual spraying (IRS) of dwellings in reducing A. aegypti populations. The residual effect of the insecticide was tested by monthly bioassays on the three most common indoor surfaces found in the Amazon area: painted wood, unpainted wood and brick. The results showed that in an area with moderate levels of A. aegypti infestation, IRS dramatically reduced all immature indices the first week after deltamethrin IRS application and the adult index from 18.5 to 3.1, four weeks after intervention (p 80% 8 weeks after application on all types of surfaces. The residual effect of the insecticide was greater on brick than on wooden walls (p < 0.05). Our results demonstrate that IRS can have both an immediate and sustained effect on reducing adult and immature A. aegypti populations and should be considered as an adult mosquito control strategy by dengue vector control program
